He wanted her. She wanted her life to end.

Calum Hood is your typical bad boy. He'll have sex with whoever catches his eye, he'll pick a fight with anyone who gets in his way, and come on, he's Calum Hood, rules don't apply to him. It's the same way for the rest of the 5sos guys, they have their own rule, which is: "No Strings Attached". They'll take advantage of girls like it's nothing, yet almost everyone in school worships them. Except for two: Emma O'Neil, and her best friend, Iris Morgan.To other girls, they're considered hot, but to Emma and Iris, they're considered fuckboys. But what happens when Emma and Calum start falling for eachother? Will they get the happily ever after Emma has always been dreaming about, but Calum has never had? Or will he just end up breaking her heart?
